HAY-LOADER.

SPECIFICATION forming part of Letters Patent No. 758,805, dated May 3,1904. Application filed August '7, 1903. Serial No. 168,607. (No model.)

To a It'll/07M it may concern:

Be it known that I, I-InxuYA. Anaus, a citizen of the United States, anda resident of Sandwich, county of Dekalb, and State of Illinois, haveinvented certain new and useful Improvements in Hay-Loaders, of whichthe following is a specification and which are illustrated in theaccompanying drawings, forming a part thereof.

The invention relates to that type of hayloaders in which there isemployed an inclined elevator and a rotating drum carrying rake orgathering teeth which raise the hay to the conveyer of the elevator; andits object is to provide yieldable means for guiding the hay to thebottom of the carrier.

The invention consists of the parts and arrangement of parts, ashereinafter described and as illustrated in the accompanying drawings,in whieh- Figure 1 is a detail side elevation, some of the parts beingshown in section, taken on the line .1 1 of Fig. 2, certain gear-wheelsbeing omitted for the purpose of clearness. Fig. 2 is a detail rearelevation of the same, partly in section.

I have not deemed it necessary to show the internal construction of thedrum or the details of some other parts of the machine not having anybearing upon the present invention.

A pair of carrying-wheels is shown at 10 10, and a frame 11 is mountedupon the axle thereof and supports the inclined elevatorframe 12. Anendless carrier or conveyer 13 turns over sheaves or rollers 14 15 atthe top and bottom, respectively, of the elevatorframe, and a pluralityof wind-guards or guideslats 16 are pivoted, as indicated at 17, at thetop of the elevator-frame and rest loosely upon the carrier, as is usualin machines of this type.

The hay is gathered from the ground by means of a drum 18, havingprojecting teeth 19 and being journaled in a frame 20, swinging aboutthe axle of the drive-wheels l0 and adjustably engaged by a bracket 21,rising from the frame 11. The drum is rotated by means of a pair ofspur-gears fixed on the axle of the drive-wheels and inter-meshing withpinions 2?) 23, mounted upon the drumshaft.

The carrier 13 is driven by means of a sprocketchain A, turning aboutsuitable sprocket-wheels, one on the axle of the drivewhcels and one onthe shaft of the drum I5, and this drum is provided with spurs 15, whichengage the hay as it is raised by the teeth 19.

A beater 29, pivoted in arms 26 26, supported by and swinging about theshaft of the drum IS, cooperates with the spurred drum 15 to raise thehay to the receiving end of the elevator. The beater-29 is driven in thesame direction of rotation as the drum 18, so as to prevent the hay fromfollowing the surface of the latter and hold it against the drum 1;).Innnediately above the beater 2%) is located a backboard 25, alsosecured to the arms 26 and serving to prevent the hay from followingover the beater and to bear it against the lower end of the carrier.

The beater 29 is driven by a sprocket-chain 30,turning over suitablewheels mounted upon the shaftof the beater and of the drum 18,respectively.

The beater and backboard are drawn forward toward the elevator bysprings 28, secured to the frame 11 and the arms 26, so that they mayyieldingly press against the hay as it is raised, thus providing anexpansible throat and cot'iperating with the drum 15 with equalefiiciency though the density of the hay may greatly vary.

Machines of this type operate most satisfactorily when the throat is socontracted that the material passes it under some slight pressure. Ifthe throat is too large, the hay will not be raised by the spurs 0f thedrum 15 until it has been bunched sufliciently to fill it. If it betoocontracted, the material rises under excessive pressure and at theexpense of increased draft. It has therefore been the practice to adjusteither the beater-frame or the carrier so as to adapt the throat of themachine to the average density of the crop. In those parts of the fieldwhere the crop was either lighter or heavier than the average themachine would necessarily do its work at a disadvantage.

In the machine as herein shown and described the beater-frameautomatically adapts itself to the condition of the crop, providing auniform pressure of the hay against the elevating-drum, and hence aconstant feed to the elevator.

Loops 27 rise from the backboard 25, the slats 16 passing looselythrough them and being thus held against lateral movement and limited intheir upward movement.

A stop for limiting the backward movement of the beater-frame isprovided consisting of a rod 31, pivotally attached'to the frame andsliding through an eye 32, attached to the elevator-frame.

I claim as my invention-- 1. In a hay-loader, in combination, anelevator, means for feeding material to the elevator, means for holdingthe material upon the elevator, and a frame independent of the feedingmeans, oscillatable to and from the receiving end of the elevator.

2. In ahay-loader, in combination, an elevator, rakes for raising thematerial to the elevator, means for holding the material upon theelevator, and a frame independent of the rakes, oscillatable to and fromthe receiving end of the elevator.

3. In ahay-loader, in combination, an elevator, a rotating rake-head, aswinging guideframe pivoted concentrically with the rakehead, and aspring holding the frame toward the base of the elevator.

4:. In a hay-loader, in combination, an eleva tor, a rotating rake-head,a swinging frame pivoted concentrically with the rake-head, a springholding the frame toward the base of the elevator, and a rotary beaterand a guideboard both carried by the frame.

5.. In a hay-loader, in combination, an elevator, a rotating rake-head,a swinging guideframe pivoted concentrically with the rakehead, a springholding the frame toward the base of the elevator, oscillatingguide-slats tor, a raking-drum having projecting teeth, a.

carrier-drum having spurs, a yielding frame swinging about the axis ofthe raking-drum, means for holding the frame toward the carrier-drum, arotatable beater carried by the frame and turning in the same directionas the raking-drum and sweeping the face thereof, and a guide-boardlocated above the beater, substantially as described.

8. In a hay-loader, in combination, an elevator, a spurred rotatabledrum at the base of the elevator, ayieldable frame bearing toward thedrum, and means for delivering hay to the throat between the drum andthe frame.

9. In ahay-loader, in combination, an elevator, a spurred rotatable drumat the base of the elevator, a yieldable frame bearing toward the drum,a rotatable member carried by the frame and coacting with the drum toraise the hay, and means for feeding the hay to the throat between thedrum and such r0- tatable member.

10. In ahay-loader, in combination, an elevator, means for holding thematerial upon the elevator, a yieldable frame bearing against thereceiving end of the elevator, and means for delivering hay to thethroat between the receiving end of the elevator and the frame.
